DISCONTINUED ITEMS

I just recently started working with Atmel’s AVR micro controllers and immediately was impressed by their powerful features. After struggling with some languages, I came across Mark Albert’s BascomAVR 1.11.64. I highly recommend that to novices and pros alike! It is a rich feature packed language at fraction of the cost when compared to others. It has an easy learning curve, especially if you are at familiar with Microsoft’s Quick Basic (the good old DOS based version!) The support from Mark himself is unparalleled considering the wide range of users.

My initial projects involve using an AVR interfacing to a MultiMediaCard (MMC) and graphic lcds. I have successfully done both at a primary level using Atmel’s development boards. The MMC is  a  2.7 - 3.6 volt device. In order to avoid voltage conversion of data lines, I decided to use an AT103L on the STK300 board. My first graphic LCD project was to interface a Sed1330F based lcd. I have the code available for that. The next two controllers will be the Toshiba T6963C and Samsung KS0108 based lcds.

Seiko-Epson SED1330F interface.

BascomAVR MMC preliminary code available here..

MMC3A (discontinued)

Please note: the MMC sockets are being replaced with the SDMMC sockets that work with SD as well as MMC cards.

On the right shown mounted on the PORTB header of the STK500 board. The pins correspond to the SS,SI,SO,SCK (B4-B7) pins of a Mega163L (3.3v) or similar AVR. No other connections are  required. The STK500 is set to 3.3v and the MMC socket is powered via the pins on the 2x5 header.

Demo software available here. Written in BascomAVR, for a Mega163L on the STK500.

The AVR_SD3

AVR_SD3

Shown assembled with an SD card (card  not included )

The 3.3v AVR_SD3 development board includes an AVR163L (or optional Mega32L ). The SD socket can also use MMC cards. Includes a standard DB9 RS232 connector for I/O.The AVC mcu can be programmed ‘in-circuit’ by using one of Atmel’s ISP programmers. All the AVR pins are available at (standard 0.1” spacing).More info...

The AVR_SD3 is a very compact 3.3v AVR controller board with an SD/MMC card socket. It can work with most 40 pin AVR-L mcus such as the  can use a Mega323L, Mega163L, Mega16L, Mega32L or a AT90LS8535 .Other “L” series AVRs can also be used with 40 pin carrier boards. The board has a standard Atmel 6 pin ISP programming header. It can be programmed using Atmels serial ISP hardware which is also compatible with the BascomAVR compiler. The board has a Max3232 RS232 IC, an I2C eeprom, 4mhz resonator, 3.3v Regulator, and a reset switch.
